摘要
As the development of new-energy power generation increases the operational uncertainty and correlation of power system, the traditional power flow calculation algorithm could not meet the requirements of power grid analysis and evaluation in this environment. A probabilistic power flow calculation algorithm is proposed, which applies the cumulant method based on Latin hypercube sampling to consider the correlation between input variables. It combines the high precision and wide applicability of analog method with the high speed of cumulant method, adopts the multi-linearized power flow model to reduce the truncation error, and applies Cholesky decomposition to solve the problem that the cumulant method can only deal with the independent variables. The simulative results of IEEE 30-bus system and IEEE 118-bus system verify the accuracy, rapidity and practicability of the proposed algorithm. © 2016, Electric Power Automation Equipment Press.
